Here is a guide on how to make your own Ferric Chloride etchant. It’s a relatively simple process that only requires some iron, hydrochloric acid, and air. As the process uses acids please be careful, and do this only if … Read more
Blondihacks wrote an in-depth tutorial on how to make PCBs made at home using pre-sensatived photo-PCBs. We especially liked the board design optimization for home etching tips. Wide traces, big vias, and using a ground plane are all strategies we … Read more
Double sided home-etched PCBs require a lot of patience and luck. Both sides need to be aligned properly, and via wires have to be soldered between the layers so top and bottom are connected. The usual process for connecting the … Read more
Ril3y left a comment on the Lincoln PCB with a few other artistic boards. Not really a “circuit” but it was an attempt at how cool I could get a pcb. Next is to bake in a circuit next time. … Read more
We enjoyed this (sponsored) segment from Make about etching circuit boards. Like Collin, we got our start etching boards we found on the web, at first with toner transfer and later UV photo masking. We didn’t know how the circuits … Read more
s3c posted this home-etched Bus Pirate v3 PCB in the forum. Nice work! Do you etch your own PCBs? We send double-sided PCBs to the board house, but still etch simple single-sided designs. Bus Pirate v0, va, and v1 were … Read more
Instructables user ArduinoFun shows how to etch PCBs at home using a positive photo-resist. This method involves printing the PCB design on an inkjet transparency, exposing it under a UV light, developing in a basic solution, then etching in an … Read more
